JAMES M. ELLIS, 0F CANTON, ILLINOIS.

EQUALIZER.

Application filed September 9, 1919.

To all whom it may concern:

Be it known that I, JAMES M. ELLIs, a citizen of the United States, residing at Canton, in the county of Fulton and State of Illinois, have invented certain new and useful Improvements in Equalizers, of which the following is a specification.

This invention relates to equalizers for use in drawing heavy vehicles or farm implcment-s.

One of the objects of the invention is to provide an equalizer which will permit the horses to be spaced various distances apart, so that the leverage may be adjusted. By my construction horses of various sizes and strength may be so placed as to permit even and uniform drawing by the animals.

Another object of the invention is to furnish an equalizer which will possess greater strength and stability than the equalizers heretofore used.

With the foregoing objects outlined and with other objects in view, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawing and more particularly pointed out in the appended claims.

Referring to the drawing Figure 1 is a top plan view of the im proved equalizer.

Fig. 2 is a rear edge view of the same.

In the drawing 1 and 2 represent parallel beams which are arranged one above the other and are connected together by bolts 3. The beam 2 is provided centrally with a clevis a and the forward portions of the ends of the beam 1 are provided with a series of apertures 5 and 6. Extending forward from the beams are two links 7 which carry at their forward ends double-trees 8, the double-trees supporting the usual swingletrees 9. The rear ends of the links 7 are connected by bolts and nuts 10 to the upper beam 1 and the bolts pass through certain of the apertures 5 and 6.

Specification of Letters Patent.

Patented July 6, 1920.

Serial No. 322,634.

In practice the bolts 10 are placed in the proper apertures 5 and 6 to accommodate the horses used in drawing the vehicle or implement and it will be understood that if light horses are placed on the left swingletrees and heavy horses on the right swingletrees, then the bolt 10 of the right hand link 7 will be shifted in the holes 5 to a point nearer the clevis 4 than the bolt 10 which connects the left hand link with the apertures 6.

If two double-trees are connected to the ends of a single beam having a clevis at its center, a tremendous strain is placed upon the central portion of the beam while in use and this frequently causes the beam to break. By my construction, the clevis is attached to the lower beam only and the double-trees are connected to the upper beam, and consequently by my construction I obtain added strength.

I am aware that various changes or modifications may be made in the construction illustrated without departing from the spirit of the invention as defined by the following claims.

I/Vhat I claim and desire to secure by Letters Patent is 1. An equalizer comprising a plurality of parallel beams rigidly connected together, a clevis connected to one of said beams only, and a swingle-tree support connected to each of the ends of the other beam only.

2. An equalizer comprising a plurality of superposed, parallel beams having their ends rigidly connected together, a clevis attached to the central portion of the lowermost beam only, the forward portions of the ends of the upper beam being provided with series of apertures, bolts engaging said apertures, links having their rear ends secured to said bolts, and double-trees con nected to the forward ends of the links.

In testimony whereof I affix my si nature.

JAMES M. EiLIs.
